libipld 1.1.1

Python binding to the Rust IPLD library

Python IPLD

This project aims to speed up The AT Protocol SDK by using Rust for the heavy lifting. Only atproto related parts are implemented first.

Code snippet:

import libipld

# Decode a CID
print(libipld.decode_cid('bafyreig7jbijxpn4lfhvnvyuwf5u5jyhd7begxwyiqe7ingwxycjdqjjoa'))
# Output: {'hash': {'size': 32, 'code': 18, 'digest': b'\xdfHP\x9b\xbd\xbcYOV\xd7\x14\xb1{N\xa7\x07\x1f\xc2C^\xd8D\t\xf44\xd6\xbe\x04\x91\xc1)p'}, 'version': 1, 'codec': 113}

# Decode a DAG CBOR
print(libipld.decode_dag_cbor(b'\xa2aa\x0cabfhello!\x82\x00\x01'))
# Output: {'a': 12, 'b': 'hello!'}

# multibase
print(libipld.decode_multibase('ueWVzIG1hbmkgIQ'))
# Output: ('u', b'yes mani !')
print(libipld.encode_multibase('u', b'yes mani !'))
# Output: ueWVzIG1hbmkgIQ

Features

• Decode DAG CBOR (decode_cid(str) -> dict)
• Decode CID (decode_dag_cbor(bytes) -> dict, decode_dag_cbor_multi(bytes) -> list[dict])
• Decode CAR (decode_car(bytes) -> tuple[dict, dict[str, dict]]). Returns a header and blocks mapped by CID.
• Decode Multibase (decode_multibase(str) -> tuple[str, bytes]). Returns base and data.
• Encode Multibase (encode_multibase(str, bytes) -> str). Accepts base and data.

Note: stub file will be provided in the future.
